In this paper, the whole process of simulation and bearing capacity of static pressure pile continuous penetration is explored under different soil conditions. The influencing factors are analyzed in order to provide reference for engineering practice.This paper first introduces the working principle of static pressure pile, and expounds its application in engineering combined with relevant literature. Secondly, based on Ansys, a finite element simulation software, the numerical model of static pressure pile continuous penetration was established, and single pile and composite pile were simulated respectively, considering the nonlinearity and layered changes in the soil layer. Finally, through numerical calculation, the bearing capacity change law of static pressure pile und...
